I am not driving my truck much at all anymore last time I drove was in the spring its been sitting ever since. I tried to start it the other day and it barely started think the cold is getting to the battery. I want to out a battery tender on it but not spend alot, and want to put one on the riding mower as well. I seen harbor freight has two models, one had decent reviews was the cheaper model for think 10 the other model was 20 had good reviews. I guess if need be I can buy one now for the truck and next pay day buy another for the mower. I just want to at least keep teh truck battery in good shape incase I need for something, plus the mower battery since it is new this year but it cost alot less the one in my truck. I checked walmart site but didn't get much may have to look in the store tomorrow. I am also looking into that mothers headlight restore kit, meguiers has a kit but at 5 bucks more but they do have a plastic buffing compound I could use with the mothers buffing ball, this way I can keep my headlights cleaned up since I drive alot at night coming home from work on dark country roads and need to see.
